what amount of room size does it heat up
8326
This is a tiny personal heater, it will heat up your hands if you put them in front of it, or put by your feet to help warm them, but it's not powerful. I don't know how it warms up a whole room, mine doesn't at all. I think a better investment would be to pay about $9 more for a "Lasko 754200 Ceramic Heater with Adjustable Thermostat" which Amazon sells. I have one in my bathroom and it works pretty good, it's also at least 4 or 5 times bigger than this one.

This is a very small space heater and is only sufficient enough for your desk top.

I don't believe it is meant to heat up a room so much as place on a desktop and keep you warm. This is how I use it and it works very well. It is small and takes up little space . It only has ON or OFF settings.

Well not much about 2-3 feet but if temperature outside is above 50 it should warm up the whole room.

Don't know about room size, but my desk area is approximately 10 x 6 and it heats the whole area up nicely, especially under my desk where it sits.

It's really just a very small personal heater meant for one person so I would say just the size of one office cubicle is the area it will warm.

Regret that i cannot answer that question. We live in a 26,000 sq foot school house with no central heat. We use a woodburner in the kitchen and use our fabulous Dr. Infrared Heater in the library which is 1250 square foot. We operate it all day,everyday and I have it on one temperature and have not changed it so far because it keeps this room livable. Maybe you could call the manufacturer. I do not know what the situation is for other people using this product but know it has been so helpful to us with this really cold winter this year.

Our room in the basement is approximately 20x25 and it heats it very well. It pretty much helps the whole basement (700 sqft) feel warmer. I love it!

Manufacturer specs say 500 sq ft. We use it in a space that is actually two rooms open to each other, a little under 400 sq ft. It seems to do a good job.

I have in a room in the garage that is 8x20ft and no problem in getting this room to 70F, takes about 10 minutes and stays there until I shut it off. Have seen other comments about this heater for room sizes up to 200 sq ft.

As a rule of thumb use 10 watts of electric heating per square foot of room space. Using that factor, the 500 watt setting can heat a room that is 50 square feet. How well the room is insulated is also a factor. 10 watts per square foot assumes the room is well insulated. Use a higher setting if that is not the case.

59* is the lowest and 88* is the highest. If the room you want to heat is bigger than a 10' X 10' the heater will have to run all the time to keep it warm. It is to small for regular rooms. I would look for one that is bigger.

The heating area is 21x14. I have found it to heat up evenly, no hot spots.

I bought one I'm happy with it however it is not made for the only heat in the room it heats roughly our livening room and kitchen and the size is 14x30 feet and that's a good 75 degrees F and on cold nights it gets the house down to 72-70 degrees F

Yes, it does heat the room a up little but, since ours is in the basement, it's a plus. I wouldn't say it heats the room up a lot but, since there's a fan running to circulate the air, the entire room is a nice even temperature. Cost depends upon the amount of usage but it's probably comparable to a small air conditioner.

I use it to heat a room of about 15' x 20' in size. It does just fine, when it is real cold outside (10 degrees or 22 degrees below freezing) it takes a while to reheat it up after a weekend or not using it a few days.

Well, like I said in my post that I have a 15x23 room and I'll tell you--I was very surprised that it heated it up as good as it did. Personally, I think this heater is the best one I've found so far. It gets pretty warm, also you can move the lever up or down to let the heat go where you want it to go. When I first get up in the mornings, I sit on the couch drinking my coffee and I put that heater in front of me and pull the lever down where the heat is going right on me. LOL--I'm not good with square feet. So what ever 15x23 is. Hope that helped.

A room about 10 ft long by 13 to 15 ft wide (130 -150 square feet) with average insulation. The 475 watt envi heater has been specifically designed to heat an average room measuring 130 - 150 square feet in floor area, to between 68 and 72 degrees, even in the coldest parts of the country. In rooms that have one or more of the following conditions: inferior insulation, many windows, staircases leading upwards, adjoining rooms that cannot be closed off (open plan) or outside entrances - this ratio may have to be lowered slightly. For rooms with above average insulation or warmer climates this ratio might be able to be increased. You can add as many heaters as you like to heat any size room, home or office. For rooms with no insulation or for rooms such as sunrooms with entire walls made of glass we recommend a ratio of one 475 watt heater per 60-80 square feet of floor area.

it warms our large living/front room. it's about 14'X28'. any bigger, it prob wouldn't reach the whole room.

Elaine - my unit heats our family room that is about 25' by 18'. It heat my much smaller office in minutes and it's 15' by 12'. It works especially well when occillating. Hope this helps.

Spark,We have been very happy with this unit. We have 3 now. It should heat room that size quite easily. Set the heater to the temperature you want, don't just set it on high because it will continue to heat the room, and it will make your room too hot...

Usually a bedroom or a closed off room... 12x12 which is what we use it for. It is a space heater for a reason. open space[2 ajoining rooms] won't cut it. it will run foreverwe also use a thermostat that we plug the unit into and we have it set at 69 degrees to kick on/off at night.
